Abstract: Mass Customisation (MC) is increasingly being touted in the global clothing industry as a key strategy to survive an ever-more turbulent market. A European Union report (Probst, Monfardini, Frideres, Demetri, Kauffmann & Clarke, 2013) estimates that five per cent of the global fashion industry will be mass customised by 2018. This growing importance necessitates its consideration in the South African context, especially as a possible opportunity for the ailing clothing manufacturing sector. Since there is a dearth of literature on MC in the South African context, an exploration into the suitability of MC as a manufacturing strategy for South African clothing manufacturers was a first step in understanding this opportunity. The competencies needed to successfully undertake MC manufacturing were drawn from the literature and were used to frame the research. Three corporate clothing manufacturers were selected as a case for this study due to the existing levels of customisation that exist in this sector. In-depth interviews were conducted in order to determine whether these firms currently exhibited the existence of the identified competencies essential to undertake MC within their organisations. One of the interviewed manufacturers seemed to have all the competencies needed to manufacture for mass customisation, whilst another very-almost did. All three manufacturers were severely affected by the dearth of suppliers and this led to the competencies identified from the literature being revised for the South African context.
